tikz extending spring with constant number of segmentsthanks for the links. the examples illustrate pretty much what I want as the final figure. However, my biggest problem is that the automatic calculation of the segment length seems to give the correct result when I print it but when I use it as an argument in "segement length=\seglength" it behaves inconsistently. I suppose that has to di with the fact that \seglength does not have cm units?
